The man left the area in a 2011 Nissan, which was located a short time later by responding officers, police said.

Four men were found in the vehicle, who were later identified as Elmer Aguilar, 18, Gustavo Rivas, 26, and Ruben Ramirez, 31, all of Concord, and David Gonzales, 23, of Antioch, police said.

A search of the suspects' vehicle yielded suspected stolen mail from multiple addresses in Pleasanton, as well as more than a dozen other cities in Contra Costa, San Mateo, and Solano counties, police said.

All four suspects were booked into Santa Rita Jail for possession of stolen property, forgery, conspiracy and drug related charges.
